>Description:
    I'm trying to package RPL/2 (http://www.rpl2.net). I have modified some script to build a standalone version but final link stage aborts with :

../rplcas/lib/librplcas.a(6-usual.o): In function `giac::erf0(giac::gen const&, giac::gen&, giac::context const*)':
(.text+0x3abd2): undefined reference to `cabsl'
../rplcas/lib/librplcas.a(6-usual.o): In function `giac::erf0(giac::gen const&, giac::gen&, giac::context const*)':
(.text+0x3b69a): undefined reference to `cabsl'

    I have tried to swap libraries invocations without any success. I have tried to add -std=gnu11. Same result. When makefile tries to link programm, it runs :

g++  -Wall -Wextra -g -O2 -mtune=native -march=native  -O3 -malign-double -mieee-fp -Wall -funsigned-char -g   -Wl,--export-dynamic -Wl,-R/usr/pkg/lib -Wl,-R/usr/pkg/gcc49/bin/../lib -Wl,-whole-archive ../tools/openmotif-2.3.4/lib/Xm/.libs/libXm.a ../tools/libXpm-3.5.9/src/.libs/libXpm.a ../tools/zlib-1.2.8/libz.a -L/usr/X11R7/lib -lXft -lXrender -L/usr/X11R7/lib -Wl,-rpath,/usr/X11R7/lib -lfontconfig  -L/usr/X11R7/lib -Wl,-rpath,/usr/X11R7/lib -lXft  -lXmu -Wl,-no-whole-archive  -o rpl

    As RPL/2 requires a fortran compiler, I have built gcc49 from pkgsrc tree :

legendre$ which gcc
/usr/pkg/gcc49/bin/gcc
legendre$ gcc -v

legendre$ nm libm.so | grep cabsl

There is not unprotected symbol.
